PG 13 for now

Prologue

The Winchester brothers stormed into a trailer that Crowley had told them to come to. As the door swinged open the boys took a quick glance around the trailer. Crowley stood over the sink and appeared to be doing the dishes. No one else was there except for a petite looking girl around seventeen or eighteen.

"Well, hello boys." Crowley said, not moving from what he was doing at the sink. At all the commotion the girl slowly raised up onto her elbows and rubbed her eyes, ones that weren't black. She looked around, stopping a few seconds to marvel at the two men who were standing just inside the door, with a knife in one's hand. The shorter one marched over to the groggy girl and held her in a headlock, ready to kill her.

"Now don't do that Dean unless you have a death wish. That girl there is my sisters great great great granddaughter, my niece. She is completely human and I am very protective of her. Let her go or I'll no choice but to kill you and Sammy over here." Crowley said, turning from the sink to look at the shorter Winchester with a sadistic smile on his face. Before Dean could let go off the girl she kneed him in the groin and slipped from his grasp, running to stand beside Crowley.

As Dean was crouched over he got to get a good look at the girl. She was maybe five six and had light brown hair like his in bouncy curls. She had Crowley's eyes, light brown only her's looked a lot less cruel and evil. "Who is she?" Asked the taller Winchester, Sam.

"As I said, my niece. I have a favor to ask you. There is another demon trying to take the title of 'King of Hell' from me and he's targeted my niece here as a hostage token. I know that you all are for saving the innocent and humans from monsters like me. Can you please take her and protect her? It makes me sick to ask you this but she's the last of my family. If you do this I'll keep the demons off your back and I'll help you with getting rid of the leviathan. They annoy me anyway. What do you say boys?" Crowley asked with a questioning look in his eyes. The Winchester boys looked at each other for a few moments, having a debate through stares. Finally Sam turned towards Crowley with a triumphant and also resigned look on his face.

"We'll take care of her. Just keep your end of the bargain." He said, holding out his hand for the girl.
